Testimonials

Grsecurity has been an essential part of our defensive strategy for years. The hardening features have kept us from being vulnerable to the majority of kernel CVEs. Mr. Spengler's analysis of kernel CVEs is in depth and timely. Grsecurity is invaluable.

We have been using grsecurity as part of our container based application streaming delivery solution for the enterprise. Grsecurity has provided us the differentiation we needed over the legacy solutions, especially in the areas of exploitation resilience and trusted execution. I would highly recommend grsecurity to anybody who wants to build a solution over a secure and robust foundation. It is a must-have.

For security-oriented webhosters like us, grsecurity is
essential. It raises the bar for common exploitation
techniques significantly and prevents most kernel-related
exploits, saving us a lot of time and stress.

When building systems that hold sensitive customer data, no other platform is as trusted by professional security engineers, like those at Immunity, than grsecurity. We have 15 years of experience breaking systems, and grsecurity has 15 years of experience protecting them from people like us.

About grsecurity

grsecurity® is an extensive security enhancement to the Linux kernel that defends against a wide range of security threats through intelligent access control, memory corruption-based exploit prevention, and a host of other system hardening that generally require no configuration.
